Considering the following figure, which of the following is a correct statement?
Answer Options
One collision domain exists with one broadcast domain.
Two collision domains exist with one broadcast domain.
Three collision domains exist with two broadcast domains.
Seven collision domains exist with two broadcast domains.
Correct Answer: C
Explanation
In the figure, there are two broadcast domains, VLAN 1 and VLAN 2. In each of the broadcast domains there exists a single collision domain, along with the collision domain between the switch and router. Therefore, three collision domains exist with two broadcast domains. One collision domain with one broadcast domain would only be true if the switch was replaced with a hub and VLANs were not used. Two collision domains with one broadcast domain would only be true if the hubs were directly connected together and VLAN routing was not in use. Seven collision domains existing with two broadcast domains would only be true if the hubs were swapped out for switches.
